Westinghouse Electric Co. has submitted revisions to the proposed design of a new nuclear reactor after the U.S. Nuclear Regulatory Commission raised concerns last month.

The company said the revisions filed Monday were "clarifications" and "minor corrections" that would not affect the safety of the AP1000 reactor. Westinghouse has contracts to build its latest reactor in Georgia, Florida and South Carolina. Utilities in Alabama and North Carolina have considered using it.

Westinghouse CEO Aris Candris said he hopes the firm is nearing the end of the licensing process.

NRC officials said last month that Westinghouse incorrectly modeled the potential stresses on several pieces of safety related equipment, including the concrete-and-steel shield building that protects the reactor.

NRC spokesman Scott Burnell said the agency was reviewing the company's latest submission.
